[Fixed]-Django migration error, trying to clean up date field with bad default

Determine what the default is in the database

cd /path/to/project
python manage.py dbshell
mysql> show create table district_season\G 
# or for postgres
# pg_dump -t 'schema.district_season' --schema-only database-name

If there is no problem with the type, run the migration with –fake

./manage.py migrate district --fake

which will mark the migration as having been run without doing anything to the database.
